A:Answer You do not say what kind of computing you are doing, but I'll look at this from a gaming standpoint. To put it simply, no. But to answer all your questions with detail, I'll start with the difference in The ending of the model names (K, F, etc.). the K suffix at the end of the i5-9600k model designated that it has been unlocked, meaning you can overclock the CPU; overclocking is a way of getting more power from a device. The F designation describes a CPU that does not have integrated graphics for mostly general pc computing. The idea behind the F design is that unnecessary power reserved for the graphics integration is not needed in PCs that are using a designated GPU (GTX 2060, 5600 XT, etc.). This in turn decreases the power consumption.
The more specific difference in the two processors of i5-i7 here are that, typically an i7 model will have either have more cores, threads; basically more computing power to Do more things AT ONCE. To be clear, the i59600k is an excellent CPU for gaming at the moment because games are not using more than 6 cores typically. This might not be true in the future so the real difference in the two from a gaming perspective is minimal, although the i7-9700f might be better suited for future benefit when more cores are utilized in games. I have a device running an i9 generation 10 processor, and running games does not improve between the two. This also depends on the other peripherals you are using. I hope this helps anyone with the same question.
